Here's their website, potentially you can call and get technical support?

As others have said, it's analog, which is fine, if you are okay with the picture quality being recorded, etc. There is a VGA device connected, which I will assume is the local monitor, which is what should show you what it is currently recording, etc.

There is an RJ45 ethernet connection to it, so likely it has an IP address that you can browse to for management. The folks at laview security can help you with a manual, etc., and/or the management login and password details, etc.

If they can't help you I can take a look and look for the manual, etc. just let me know.
